MACHINE FOR WINDING- BOBBINS.

aereos.

To all whom t may concern:

Be it known that I, JOHN R. FITTON, a citizen of the United States,residing at Worcester, in the county of Worcester and Commonwealth ofMassachusetts, have invented a new and useful Improvement in Machinesfor Winding Bobbins, of which the following is a specification,accompanied by drawings forming a part of the same, in which- Figure 1represents a front elevation of a bobbin winding machine embodying myinvention, showing such parts as are directly concerned in carrying myinvention into effect. Fig. 2 is a diagrammatic view showing therelative position of the revolving bobbin, its driving cylinder, andfeed rolls.

Similar reference letters and figures refer to similar parts in thediierent views.

The object of my present invention is to provide a means by which theyarnv may be wound in opposite directions upon the bobbin at will, toenable such bobbin to be used in connection with shuttles provided witha cutting device, arranged to be engaged by the yarn when the reversetwist is reached in unwinding the yarn from the bobbin. To accomplishthis purpose I provide means for rotating the bobbin first in onedirection and then in the opposite direction in order to reverse thewind of the yarn and at the same time maintain a uniform direction ofthe strand to be wound as it is delivered to the bobbin.

My invention is applicable to any style of quiller or spooler and alsoto a spinning frame by which the yarn strand is twisted and wound uponthe bobbin.

My invention comprises means for rotating the bobbin, means for feedingthe strand to the bobbin, means for reversing the bobbin at will and atthe same time maintaining a uniform feeding of the yarn to the bobbin.

In the accompanying drawings I have illustrated portions of a bobbinwinding machine which show a rotating bobbin, a cylinder for driving thesame, rolls for feeding the yarn strand to the bobbin, which vmay be thedrawing rolls of a spinning A frame, and a controlling mechanism operated by a single shipper whereby the direcltion of motion of the bobbinis changed withoutchanging the direction in the-rotation Specication ofLetters Patent.

of the feed rolls, leaving out all other mechanism which are usuallyemployed in a spooler or spinning frame, such as twisting mechanism andmechanism for laying the yarn upon the bobbin, as these are not directlyconcerned in my present invention.

Referring to the accompanying drawings, 1 denotes a portion of theframework, 2 a revolving cylinder having a belt connection with aspindle mounted in astep 3, and carrying a bobbin 4, on which the yarnstrand 5 is wound. Above the bobbin are rolls 6, 6a and 6* between whichthe yarn strand passes, said rolls being rotated to impart a feedingmovement to the strand 5 in the direction of the arrow a. The cylinder 2is carried upon a shaft 7 on which the pulleys 8 and 9 turn loosely, andare driven in opposite directions by open and twist belts from aconvenient countershaft. The pulleys are provided with hubs having teethand forming clutching members 10 and 11 which are alternately engaged bya sliding clutch collar 12 having a spline connection with the shaft 7.Turning loosely upon the shaft 7 is a sprocket wheel 13 and a gear 14,provided with toothed hubs forming clutching members 15 and 16, whichare alternately engaged by a sliding clutch collar 17 having a splineconnection with the shaft 7. The sprocket 13 has a direct chainconnection with a sprocket 18 attached to the shaft 19 of the roll 6.The gear 14 engages a gear 20 turning loosely upon a stud 21, and to thehub of the gear 2O is attached a sprocket 22 having a chain connectionwith a sprocket 23 attached to the shaft 19 of the drawing roll 6. Therolls 6 and 6EL are geared together through an intermediate gear 21 tocause both rolls to turn in the same direction, and the roll 6b restsupon the yarn strand. The sliding clutch collars 12 and 17 are operatedby shipping levers and 26, pivoted at 27 and 28 and moved simultaneously by a pivotally connected sliding shipper rod 29. By sliding theshipper rod to the right the shaft 7 is connected with the pulley 8,causing the cylinder to be rotated in one direction and by slidingI therod 29 to the left, the shaft is connected to the pulley 9 and thecylinder 2 will be rotated in the opposite direction. As the clutchcollars 12 and 17 slide simultaneously the sprocket 13 will beconnectedv with the, shaft 7 together with the pulley 8, and the gear 14toget-her with the pulley 9. The sprocket 18 drives the shaft 19 in onedirection, while the gear 14 is turned loosely on the shaft 7 owing toits connection with the shaft 19. lVhen the shaft 7 is turned in theopposite direction the shaft 19 is still rotated in the same directionas before, by means of the gears 1-t and 20, the sprockets 22 and 23,while the sprocket 13 is then rotated loosely on the .shaft 7.

The machines to which my invention is especially designed, comprisemeans for rotating the bobbins for the purpose of winding yarn thereon,embodying a common shaft with which the bobbins are connected, and meansfor feeding the yarn strands toward the bobbin.

I do not confine myself to the precise construction and arrangement ofthe driving mechanism for rotating the bobbin and the feed rolls, or tothe specific construction of the shipping or clutching mechanisms. Theobject of my invention will be attained by providing` means forreversing the direction of the bobbin driving shaft or cylinder by whichall the bobbins are simultaneously reversed, and also by providing meansfor reversing the bobbins and maintaining the feeding movement of theyarn strand in the same direction.
